Humans move with hinges and levers, however the putting stroke movement mostly contradicts these natural hinge actions. The BI 3 Putter is specifically designed to promote a stroke based on the hinging of and rotation around, the spine with good weight distribution. BALANCE and STABILITY along with CONSISTENT SET UP position are proven elements for Pecision Putting.

The BI 3 putter includes features to enhance this process:

Flat sole that sits on the green in a fixed position

Special shaped sole that promotes the correct stroke

Fixed lie angles forces consistent balanced set up both left/right and heel/toe

Special grip that promotes consistent connection to the putter

A set up that promotes a Pendulum stroke following the spines hinge with anti-sway

BI 3 set up to the correct elements of bio-mechanics promotes repeatable stroke

The BI 3 "optics" connect with the muscles and hinges via the brain to make a loop of visual input and physical output for a steady controlled acceleration on a consistent stoke plane

Specfic BGA grip design can also accommodate variable grip styles and stroke actions and improve consistency in these as well

The BI 3 Putter is designed from extracting all the major components of OPTICS, PHYSICS and BIO-MECHANICS see the research data for more information. See Research on Weight Distribution here Reference material - Bio-mechanics
